Crashes when attempting to use

[baroldgene]

Copied the standalone lazy.nvim config and when attempting to run it for the first time I get this error:

msg_show.lua_error Error executing Lua callback: vim/_editor.lua:0: nvim_exec2(): Vim(undo):E438: u_undo: line numbers wrong

Happy to help troubleshoot but honestly don't know where to start given the error. Here's my lazy config:

  {
    "debugloop/telescope-undo.nvim",
    dependencies = { -- note how they're inverted to above example
      {
        "nvim-telescope/telescope.nvim",
        dependencies = { "nvim-lua/plenary.nvim" },
      },
    },
    keys = {
      { -- lazy style key map
        "<leader>fu",
        "<cmd>Telescope undo<cr>",
        desc = "find undos",
      },
    },
    opts = {
      -- don't use `defaults = { }` here, do this in the main telescope spec
      extensions = {
        undo = {
          -- telescope-undo.nvim config, see below
        },
        -- no other extensions here, they can have their own spec too
      },
    },
    config = function(_, opts)
      -- Calling telescope's setup from multiple specs does not hurt, it will happily merge the
      -- configs for us. We won't use data, as everything is in it's own namespace (telescope
      -- defaults, as well as each extension).
      require("telescope").setup(opts)
      require("telescope").load_extension("undo")
    end,
  },

I also tried the instal variant where it's added directly to the telescope include. No change.

This seems to work on code files but breaks on my markdown files within Obsidian. Maybe some sort of conflict there?

[debugloop]

Same issue as here: https://github.com/debugloop/telescope-undo.nvim/issues/59

I really need to get around to implement the suggestion made over there, sorry about the inconvenience, I'll handle it later this week 👍🏻
